A 41-year-old man was found fatally slashed in the neck in his Hell’s Kitchen apartment today, police said.

Police went to the West 46th Street building at 2:30 p.m. after colleagues reported that the man hadn’t shown up at work for a few days.

The door was locked but a cop went through the second-floor window and discovered the unidentified victim bleeding from the neck and lying on the floor next to a blood-soaked bed. He was pronounced dead at the scene.

His shirt was missing. A knife was found at the scene. Police said there was no sign of a break-in.
